When extreme values are present in a set of data, the mean and standard deviation may not be appropriate measures of central tendency and dispersion. This is because extreme values can greatly influence the mean, making it an unreliable measure. Instead, the median and interquartile range are better measures as they are not as sensitive to extreme values and give a more accurate representation of the central tendency and dispersion of the data.
